There are 3 formats available: .pdf (original), .txt (clean text), and .brf (braille file). See the "all files HTTP" link to access all three; also go there to read the .txt file if the "full text" link gives trouble.
During the editing process, a diligent attempt has been made to correctly discern every reference character, date, measurement, etc. set forth in the patent, and the majority by far are correct. However, because the OCR process is not entirely accurate and because inference is difficult at times, there may be some that are inconsistent or incorrect.
In the .txt and .brf formats of this patent, a stand-alone or punctuated dash denotes a word or phrase that could not be deciphered. .
